How to handle persistant fields of interfaces?

Hi,
I have a persistent class A which holds a reference to an interface I. This
interface is implemented by two other persistant classes B, C.
class A
private I myI;
class B implements I
class C implements I
Is it possible to make the member myI persistent?
Thak you very much for helping.
Regards,
Thomas

Kodo 2.4 has support for 1-1 relations to interfaces that are implemented
by persistent classes. Kodo 2.3 also has support, but only be serializing
the related object to a BLOB column.

How to handle Custom field added in BP : Role Bill Account

Hi Friends,
I am working on an interface which creates Bill Account role for a BP but the problem is there are about 15 Custom fields added to standard BP transaction in BA role.
As I am using BAPI_BUPA_FS_CREATE_FROM_DATA2 for creating the BP and
BAPI_BUPA_CENTRAL_CHANGE for changing the BP role Bill Account?
Can anyone tell me how to handle those custom fields in the existing BAPIs or there is some other way of doing it?
Thanks in advance,
Pradeep
Note : Helpful answers will be rewarded.

Hi,
I have seen these BAPIs but are they used with normal BAPIs for BP creation and change.
For example : I create the BP using BAPI_BUPA_FS_CREATE_FROM_DATA2 and for the Custom fields I should use these BAPIs as suggested by you alongwith the create BAPI.
And will it work for Changing the BP also.
Kindly clarify.
Regards,
Pradeep

How to handle message prioritization in interface determination

Hi Experts,
How to handle the prioritization of messages if we say that for single source message it will be forwarded to 2 types of target messages.
Here's the scenario:
InterfaceDetermination object
SourceMessageA => TargetMessageTypeA
SourceMessageA => TargetMessageTypeB
Since both of the target messages will receive the source message, i want to prioritize that TargetMessageTypeB will be receive it first before TargetMessageTypeA.
Should I structure it in the Interface Determination as this:
SourceMessageA => TargetMessageTypeB
SourceMessageA => TargetMessageTypeA
or this should be handled by BPM? Let say BPM is the last option how could this be configured in ID?
Cheers,
R-jay

Hello Folk,
you have once option in the interface determination check the maintanence order at runtime , it will solve your problem.

How to handle Mandatory field in a FORM

Hi,
Version - Forms Builder (9.0.4.2.0)
I just want to know the best practice to handle mandatory field in a FORM.
Because if we put required property to 'yes' then can we input message there without writing validation in WHEN-VALIDATE-ITEM trigger.
In one of form I have; cursor couldn't move without entering that form. (even we set to Required property to No) How do this happen.
rgds
shabar

Hello,
If you want to replace the Forms standard message, you can write an item/block/form level When-Validate-Item, then remove the mandatory property from the item.
If you let the property to YES, you can write a block-level ON-ERROR trigger to change the message:
declare
     lv_errcod NUMBER := ERROR_CODE;
Begin
     if lv_errcod = '40202' Then
          Message('You absotutly HAVE to enter this field');
     else
          Message('err:' || lv_errcod );
     end if ;
end;Francois

How to Handle Blank Field Value based Condition in SmartForms

Dear Sir,
In SMARTFORM , we need to define a Condition that incase Field Value is not equal to BLANK value (blank means that field is empty) then a specific text gets printed .
Our problem is that We do not know as how to define Empty Field Value based condition .
Had it been Non Empty Field value based condition then solution was simple and could be done in following way :
Field Value                        R                     Comparision Value
WA_KZDKZ                      =                      'X'
In our case , we need to give Blank (Empty Value) instead of 'X' .
Kindly help us pl .
Rgds
B Mittal

Hi,
To handle blank field values in SMARTFORMS,
Go to the conditions tab in your SMARTFORM and give condition there
Field                Comparision operator          value
<Field name>      <> Here symbol is diff     space.
eg:
wa_mara-matnr    =/                                   space.

Q) Now My question is How to update all the values.
Eg: Create procedure procdname (ip_allvalues in typerecord)
is
begin
--statements;
end;
the above procedure input parameter can handle all three fields data when they pass,
1) If the parameter handles, which type i need to create ?
2) How i need to update multiple records at a time?
Please can any body...
Thanks in advance..

Q) Now My question is How to update all the values.With an update statement. Identify the row with a where condition and then set the new values. That's one of the first reasons why primary keys are used.
1) If the parameter handles, which type i need to create ?
2) How i need to update multiple records at a time? If you don't explain how you User Interface is designed to work nobody can tell you anything about it. Anyway for such things there is no need to define any type.
Usually the application should submit an update command(like the following one) for each row to update.
update <table_name>
     set field_1= <value1>,
          field_2= <value2>
          field_n= <valuen>
where <primary key column> = <primary key value of the row to update>Bye Alessandro

How to handle BLOB field in receiver JDBC adapter into ABAP table

Dear Experts,
I am working in a synchronous scenario with Sender ABAP Proxy to Oracle Database as receiver via SAP PO 7.4.I will be calling a stored procedure view with fields ID, NAME,Age,*** and BLOB (Image binary).
1. The response from Oracle Database field BLOB is to be stored in ABAP table.Would I have to write any JAVA program to read the BLOB or the receiver JDBC adapter will handle it and store in a table by using ABAP proxy once it reaches ECC.
2. If yes, would the JAVA program have to deal with other 4 fields.
3. Can I use a UDF mapping to this BLOB field.
Regards
Rebecca...

Dear Praveen,
Thanks for your response...
Please correct me if I am wrong.
1. For 1-1 response mapping for BLOB field, I will use just use the below UDF code.
public static byte[] hexStringToByteArray(String s) {
            int len = s.length();
            byte[] data = new byte[len / 2];
            for (int i = 0; i < len; i += 2) {
                        data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
                                                                                     + Character.digit(s.charAt(i+1), 16));
            return data;
2. ===Using the byte data, create binary attachment in mapping for abap proxy response===
Could you please share how to create the binary attachment.. I am not clear

How to handle Lookup Field in Add / Edit Forms

I have a list of properties and a photo library where each image has a 'property' column that defines which property it pertains to.
I've customized the DefaultDisplayForm and added a web part to show the images from Photo library related to the selected property. This works because I've "connections" so that filtering takes place (the property list "Provides
Row" to the Photos Web part which obtains 'Filtered Value from' the selected property
While this works fine, I am not sure how to extend this so that
1) Modify the DefaultEditForm so that user can drag / drop additional photos to the Photos List View web part, and have the lookup field be populated automatically.
2) Modify the DefaultAddForm to allow user to drag / drop photos for a new property (using drag drop) and have the lookup field be populated automatically.
3) Modify the DefaultDisplayForm to disallow the user from adding photos using drag / drop (i.e.l to force them to use the Default Edit Form to do this).
I would imagine I need to add some JavaScript snipped that sets the value of the lookup field in each photo being uploaded to the Property selected in the other webpart but I am not sure where I should do that ?
Any guidance appreciated.,

Hi,
As there is no such OOTB feature can meet your requirement, it will need some customization with the REST API and JavaScript to implement the effect of drag and drop and the
auto-populated functionality.
Here is a demo about how to use the HTML file upload control to perform the picture uploading with “drag and drop”:

How to handle empty field in idoc to file scenario

some field of IDoc is empty, there occurs error. like
<Trace level="1" type="T">com.sap.aii.utilxi.misc.api.BaseRuntimeException: RuntimeException in Message-Mapping transformation: Cannot produce target element /ns0:vendor_list/vendor[3]/company_code. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd at

Hi Shen,
You can do this in two ways :
1.If you are above XI3.0 SP14 then you can use the node function "mapWithDefault" in between the mapping. This will create the xml tag for the field on the target side even if you are not having those fields in the source side i.e., idoc.
2.At first check your field exists or not at runtime & based on that If exists then you map it to the target field else if you dont have then if the field is alphanumeric then map the same length spaces as constant in the target or if the target field is numeric then map with a constant having that many no. of zeros.
Ex:
If>Idocfield>Exists>then>Idocfield
>else>constant(may be with spaces or zeros)

How to handle error in Syncronus interface?

I think JDBC adapter does not support application interface.
So you can only access the error text of system fault exception.

How to handle empty Dats field received from SAP RFC response

Hi All,
I am invoking a SAP RFC which gives me a Dats field in response.
A valid dats fields is successfully received by my pipelines.
But when an empty Dats field is received, My pipeline fails and i get error.
How to handle the empty Dats field from SAP

Hi Anant,
This is because the legacy SAP adapter accepted RFC messages with date field empty. In the new version, the same call results in an error. WCF-SAP adapter doesn't allow blank XML nodes.
You need to use the below custom pipeline component as a workaround.
Refer:
Pipeline component for enabling legacy behavior in WCF-SAP adapter.
